Hi! I tried to make a script that craft a house from the stone and wood that i collect , but when i collect all items needed the button to build dosen't apear . Can someone tell me why? . Thanks !

Collect stone/wood script #pragma strict

private var inventory : Inventory;

function Start () { inventory = GameObject.Find("First Person Controller").GetComponent(Inventory); }

function OnTriggerEnter(hit : Collider){

if(hit.gameObject.tag == "Player"){ inventory.wood += 1; Destroy (gameObject); } }

house script

pragma strict

var house : GameObject;

private var inventory : Inventory; private var showGUI : boolean = false;

function Start () { inventory = GameObject.Find("First Person Controller").GetComponent(Inventory);

if(inventory.wood >= 2 && inventory.stone >= 1)

GUI.Box(Rect(Screen.width/2 -75,Screen.height/2 - 12.5, 150,25), "Press B to Build");

if(Input.GetKeyDown("b"))

house.SetActive(true);

}

Inventory script

var wood : int = 0; var stone : int = 0;

function OnGUI(){ GUI.Box(Rect(0,0, 100,25),"Wood: " + wood); GUI.Box(Rect(0,25, 100,25),"Stone: " + stone); }
